The results showed that resistant gene Ht in F1 heterozygote was the most effective on controlling spots number and size; all monogene in heterozygote could produce spore by moisture culture and resistant gene Ht1 was the most effective; resistant gene Ht1 in medium level, Ht3 in high level, and Ht in low level of vertical resistance of heterozygote, were the most effective on controlling spots spread; while Ht2 in high level of vertical resistance of heterozygote was the most ineffective on controlling spots spread; and all resistant monogene in heterozygote showed superior to their parents on controlling incubation period and gene Ht was more significant than other genes.

结果表明，抗性单基因Ht处于F1代杂合状态时，控制病斑数和病斑面积的效应最强；单基因处于杂合状态时，湿培48h病斑全部能产生分生孢子，且处于同一水平抗性杂合状态时，Ht1控制产孢量的效应最强；Ht1处于中水平、Ht3处于高水平和Ht、处于低水平垂直抗性杂合状态下，控制病斑扩展效应最强；而Ht2处于高水平垂直抗性杂合状态下，控制病斑扩展效应最弱；抗性单基因处于杂合状态下，控制潜伏期多表现超亲现象，Ht控制病害潜伏期比其它单基因显著。

Amino-monomethoxypoly(ethy1ene glycol)(mPEG-NH2) was synthesized based on the principle of Gabriel synthesis.Monomethoxypoly(ethy1ene glycol) tosylate was prepared at first,and then reaction with potassium salt of phthalimide as nucleophile to produce the monomethoxypoly(ethy1ene glycol)phthalimide derivative.
